  • Ortiz, X.A.; Smith, J.F.; Bradford, Barry J.; Harner, Joseph P.; Oddy, A. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2008)
    Developing management strategies for Korral Kools will help producers provide cooling in the housing area while minimizing the operational cost of the Korral Kools system. Two experiments were conducted at a dairy in ...
  • Irsik, M.; Langemeier, Michael R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2003)
    This study examined the impacts of animal health and death loss on the economic performance of feedlot cattle. Using data from two feedlots in western Kansas, the impact of animal health on economic performance was ...
  • Abdelgadir, I.E.O.; Cochran, R.C.; Vanzant, E.S.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    We evaluated the potential of several commercially available proteases for use in predicting the undegradable intake protein (UIP) concentrations o f alfalfa and prairie hay. Protease s differed in their estimates o f ...
  • Newton, E.A.; Stevenson, Jeffrey S.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    In two different experiments, we studied the influence of: 1) separating litters from their dams (altered suckling) during the last 8 days of lactation, which included a change in housing and social interaction with other ...
  • Stevenson, Jeffrey S.; Schmidt, W.E.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1981)
    Onset of estrus in gilts fed allyl-trenbolone for either 14 or 18 days was controlled effectively. The stage of the cycle at the beginning of treatment had little effect on the synchronization response. More than 97% of ...
  • Davis, Duane L.; Stevenson, Jeffrey S.; Schmidt, W.E. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1983)
    Gilts were artificially inseminated on the fifth, sixth and seventh days after estrous synchronization with altrenogest (scheduled AI). Contemporary controls also were synchronized but were checked for estrus twice daily. ...
  • Tonn, S.; Groothius, P.; Boese, B.; Blair, R.; Davis, Duane L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1994)
    The problem of reduced reproductive performance in sows weaned at 5 to 11 days (early weaned) after farrowing was assessed by comparing estrous and embryonic traits in these sows and others weaned at 23 to 31 days ...
  • Lamb, G.C.; Miller, B.L.; Traffas, V.; Corah, L.R. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1997)
    In April, 1996, 1501 yearling crossbred heifers located on seven different ranches were estrus-synchronized and artificially inseminated (AI) 12 hours after they were detected in estrus. Herd size ranged from 82 to 43 ...
  • Kiracofe, G.; Koch, B.A.; Hines, Robert H. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1968)
    Several methods of synchronizing estrus have been tried in swine. One of the oldest and most commonly used natural methods is weaning pigs from a group of sows simultaneously. When this is done, the majority of sows will ...
  • Simms, D.D.; Sprott, L.R.; Odde, Kenneth G.; Corah, L.R. (Kansas State University. Agricultural Experiment Station, 1982)
    In 22 field trials involving 1,692 cattle, we evaluated Lutalyse as an estrus-synchronization agent for both natural mating and artificial insemination. Only 52.7% of the females in all 22 trials were cycling at the start ...
  • Larson, J.E.; Lamb, G.C.; Geary, T.W.; Stevenson, Jeffrey S.; Johnson, Sandra K.; Day, M.L.; Kesler, D.J.; DeJarnette, J.M.; Landblom, D.G.; Whittier, D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Our objectives were to determine whether a fixed-timed artificial insemination (TAI) protocol could yield similar fertility rates to a protocol requiring detection of estrus and whether an injection of gonadotropin ...
  • Larson, J.E.; Lamb, G.C.; Stevenson, Jeffrey S.; Marston, T.W.; Johnson, Sandra K.; Day, M.L.; Geary, T.W.; Kesler, D.J.; DeJarnette, J.M.; Schrick, F.N.; Areseneau, J.D. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    Our objectives were to determine whether a fixed-time artificial insemination (TAI) protocol could yield pregnancy rates similar to a protocol requiring detection of estrus and whether inclusion of a CIDR (a vaginal insert ...
  • Smith, J.F.; VanBaale, M.; Jamison, C.; Rodriguez, R.; Harner, Joseph P.; Brouk, Michael J. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2006)
    A project to evaluate the degree of heat stress in individual dairies was carried out in the summer of 2005. The object of this project was to develop a method to evaluate or audit how effective an individual dairy is in ...
  • Main, R.G.; Minton, J. Ernest; Tokach, Michael D.; Goodband, Robert D.; Nelssen, Jim L.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2001)
    We conducted two trials to evaluate the effects of feeding graded levels of cloves to weanling pigs as a substitute for antimicrobials. In the first trial, improvements in ADG were observed in pigs fed the lowest level ...
  • Whitham, N.G.; Coetzer, C.M.; Hunter, R.D.; Drouillard, James S.; Blasi, Dale A.; Titgemeyer, Evan C. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1999)
    A 99-day study was conducted to evaluate growth performance of 216 beef heifers (average 524 lb) fed traditional roughage-based diets at 2.75% of body weight or limit-fed highconcentrate diets containing corn or corn ...
  • Dunham, James R. (Kansas Agricultural Experiment Station, 1989)
    A computer program was developed for analyzing DHI records to evaluate potential losses from 1) reproduction, 2) nutrition, 3) milk quality, and 4) genetics. Production-tested Kansas Holstein herds were grouped according ...
  • Neill, C.R.; Groesbeck, C.N.; Lawrence, K.R.; Hastad, C.W.; Gottlob, R.O.; Hildabrand, B.M.; Nelssen, Jim L.; Tokach, Michael D.; Goodband, Robert D.; DeRouchey, Joel M.; Dritz, Steven S. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 2004)
    A total of 224 nursery pigs (PIC L 327L × C22) initially 12.9 ± 3.0 lb and 21 d of age were used in a 28-d feeding trial. The objective of our study was to evaluate the effects of oregano oil, with or without an in-feed ...
  • Boyd, G.; Corah, L. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1987)
    Results from two trials showed that serving capacity (SC) can be successfully evaluated in yearling beef bulls under field conditions and is influenced by sire line (P<.01). Also, providing sexual experience to low ...
  • Gross, K.; Harmon, D.; Avery, T. (Kansas State University. Agricultural Experiment Station and Cooperative Extension Service, 1988)
